The B<xdcp> command concurrently copies files to or from remote target
nodes. The command issues a remote copy command for each node or device specified. When files are pulled from a target, they are placed into the target_path with the name of the
remote node or device appended to the copied source_file name. The

If using hierarchy, then xdcp runs on the service node that is servicing the compute node. The file will first be copied to the path defined in the site table, SNsyncfiledir attribute, or the default path /var/xcat/syncfiles on the service node, if the attribute is not defined. The -P flag will not automatically copy
the files from the compute node to the Management node, hierarchically. There
is a two step process, see B<-P> flag.
